Poor, poor Al Gore.
The once and never-again political leader-turned-"scientist" has been on the business end of some stern debunkings (for example) since his cinematic sandwich board, An Inconvenient Truth, hit the silver screen.
The definitive debunking to date, both in content and credibility, I think comes to us from Joseph D’Aleo, a fellow of the American Meteorological Society and the first director of meteorology at the Weather Channel (read: can’t be accused of being a "big oil" shill.) D’Aleo is unimpressed with Al’s "truths" and offers the armchair climatologist a few inconvenient truths of his own. For example:
The former director of the American Association of State Climatologists indicated that 75 percent of the state climatologists believed other cyclical factors were more likely responsible for warming. An international survey found that fewer than one in 10 climate scientists believed that climate change is principally caused by human activity.
When confronted with contrary evidence, Gore and others refuse to rebut the evidence and instead attempt to paint those who disagree with them as either outside the scientific mainstream or bought-and-sold by energy companies. The film takes it one step further, suggesting that those who speak out on global warming are somehow being muzzled, their message blocked. Nothing could be further from the truth.
It appears that mainstream climatologists hold a view far closer to that of mainstream Americans and it is Al Gore and his gang of political phonies who are living on the extremes. And D’Aleo minces no words in calling the mad pseudo-scientists out:
"An Inconvenient Truth" is more political polemic than serious scientific study on the complex issue of global climatology, meant to spur public policies to reduce human impact on the environment. While the film will surely attract activists from both major political parties, the vast majority of Americans will be caught in the middle, left to wonder what the appropriate policies should be to address a problem that is being overstated for political gains.
And thus does Al Gore become to climatology what Dan Brown is to theology.
